and thi 1 s providing adequate elasticityifor 1mi GLS .that part-of the ring whichis more irrimediately associated with the tread. Itwill be noted that with the tubular ring 10 Secured as described therportion 11 occupies ya, position at the side of the transverse horizontal axis of the tube op osite to that where the tread is located, wit i the result that the free resilient part of the ring'is'di'sposed bto' bee.

sensible of compression exerted at any point tachable or otherwise, a supplementalspringmetal section 13, extending circumferentially around the ring 'and preferably having its ends united to accord with the continuous character of the ring. This sup lemental sectin 13 is corrugated `and is'sliown of such width that besides providing for the corrugated vfeature referred to and normally afordinga transversely-extended clearancell space 1-4 between it and the resilient part of t e ring the edge portions 15 16 of said section bear upon and are secured to said free resilient part at points approximate to the transverse horizontal axisv of the ring, small machine-screws 17 being indicated as one form of securing means.` The section 1B may present a luralityof corrugations, the

",jj'arrangement il ustrate'd, providing for central and side corrugations'lS, 19, and 20, re-

`spectively, -longitudinally disposed and in .j' extent Aparallel relation. The' corrugations need -notnecessarily extend longitudinally nor be parallel.

The contour and relatively excessive area of the section 13 render it stiffer' than the resilient part of the ring, and hence when compression is encountered said section through 1ts connections with'said part causes the latter to yield, vand thus afford an easy cushioning eii'ect.` As the compression further increases the section will be forced back upon lthe free part, said section meanwhile becoming more rigid and at the same time causing the free art of the ring to yield, but to an ess than previously. Ultimately "-f'under accumulative compression the free part will have become usufliciently unyieldmg to resist further movement by the section, whereupon inwardly-extending bends 21 of the latter intermediate of the central and side corrugations will bear upon the now comparatively rigid free part and result in the ilexible i `aterial embodied inthe tread portion of the envelop or shoe 'Z2 flowing and accommodating itself to the general outline externally presented by said section, wheresaid tread portion will acquire for the time being pronounced alternate ridges vand depressions, which will greatly enhance the tractive capacity of the tread.

The securement of the ends of the section 13 in the ina-nner stated provides for said section moving bodily with the free part of the ring, while the relative sliding of the section ends onthe surface of said free part is prevented, and hence chafing and heating from this cause are avoided. lt will also be appreciated that the absence of the corrugated feature from the free part obviates any tendency of the spring portions of both the section and said free part from becoming un- "der any compression mutuallyv engaged or interlocked, which latter condition would interfere with or tend to negative the freedom of spring movementl of which both said sec-l tion and said part are more or less independently capable.

While any suitable envelop or covering may be employed in connection with a tubular spring-metal ring possessing all or some of the novel characteristics previously described, the envelop or covering illustrated is in the form of a shoe 22 of yielding material, such as rubber or 'any of its elastic compounds. Such shoe may be of composite character and embody one" or more thicknesses of canvas or other suitable fabric. The shoe is shown as generally comprising inner and outer layers 23 24, united byvulcanization to firmly confine between them contiguous to the shoe-tread a transverselyextended and longitudinally-continuous armor 25, which should be of some material and so conditioned that while promoting the durability of the shoe it will at the-same time be suliiciently flexible' to permit the tread portion while under compression to conform to the corrugations and depressions of the supplemental metal section 13, as previously explained. One arraneement of such armor consists of a series ofthin vstrips of cane or equivalent material closel woven and presenting diagonally-crosse transverse, and long itudinally-extended strands.

It will be observed that the major thicknesses of material forming the shoe are present both at and adjacent to the tread portion, the latter being the part wherel increased thickness is important both for wear purposes and for augmenting thecushioning effect obtained in connection with the inclosed spring-metal ring. The tread portion in Fig. 1 normally presents a moderatelycurved surface, which is prolonged at each side by the integral lateral enlargements 26, such configuration lof tread upon a slight compression providing practically a broad flat cushion-bearing for the wheel conducive to the easy travel of the vehicle. The corrugations 18, 19, and20 of the supplemental metalsection '13 by bearing against the interior surface of the inner layer 23 contribute IOO g' to-support and brace the tread portion' ofthe rounded to adapt the lower parts of said por- 'ro tions for snugly conforming within the metal 30, with the overturned curved edgesV 31 thereof taking over and engaging theA shoulders. l Tapering blocks or sections 32 jare interposed, between;A the portions 27, so 1 5 that the latter are mutually spread to maintain .them engaged by the rim, and for ren- -dering such portions sufficiently rigid for such, purpose longitudinally-disposed fillingpieces 33 are inclosed within the portions 2 7.

'zo These lling-pieces may be of a 'cross-sectional sha e, so that they will.. generally accord wit f the cross-sectional character of the base portions of the shoe and insure said portions eing forced into their engaged positions 25 Without liability of theircbeco'ming lbuckled or not being uniformly held. The pieces/33 may be introduced in 'position by insertion,

or they may be molded in the shoe duringthe manufacture ofthe latter. .Said pieces can 3o be of any satisfactory material, such as rubber stiffer than that otherwise embodied in the shoe, or compressed ber, metal,v or tough wood may be used.

The blocks 82, which will preferably be o 3 5 some durable rigid material-such as wood, compressed fiber, metal', ortho like-need not T the Jfull depth of the'space between Aoe portions 27 but can vprimarily stop at short of theri'in-bottom to permit 4o' quent .downward :movement of said bloclsin order to tighten the shoe portions in their engaged positions in the operation of bolting the parts together or in the event of' said portions becoming loose through wear, 45 shrinkage,or other cause. Said blocks are regularlyspaced around the Wheel and form, in lconnection in thetubular spring-metal ring, shoe-base, and rim, a circular series of intermediate' spaces 34. The ring, shoe,

5o blocks, rim, and the feuy 35 are ai rigidly clamped together in the operative relation disclosed in the drawings by bolts 36, which extend through appropriate openin s in the ring, blocks, rim, and felly and iirm y clamp 5 5 the same together through the medium of the bolt-heads 37 and securing-nuts 38 on lthe externally-projecting portions of the -bolt-shanks. Each bolt-head 'may be conditioned to bear directly upon the inner part 5o of the ring 10; but in the arrangement'shown an arched section 39, of metal, is .provided for each bolt and has its parallel lower edges bearing on the interior surface of the ring, so

' that saidsection spans the contiguous bolt- 65 opening in the ring-to the end that the bolt will extend through asomewhat elon ated longitudinal slot 40 'in thef'section, an the' bolt-head; which is transversely curved, 4will decreased length to avoid vundue cutting awa `bear on the top. of said'section. The bolt- .openings '41 and 42 in the ringlO'andf in each 7oA of theparts m which said slots are 'forme yand yet provide slots adequate for the convenient introduction and removal ofthe particular bolt employed. v-

`The description immediately preceding,

including the reference tothe character and relation of the slotted sections 39, blocks 32, and ring l10, will render the-manner in which the several parts are assembled and` bolted together readily com rehended. -With one o f the portions- 27 o the shoe-base disengaged and turned back to expose the-continuous opening-presentedin the tube Iside between the edges 11 12 the successive bolts can, while each `is held in ahorizontal 'posipropriate tool, be laterally introduced-Within the tube, after which, said bolt ,can be soma- 'tion through the instrumentalityof an -ap-A nipulated thatit's shank will becaused to dei scend through the several slots of thasection 10, ring and block beneath, and entergand move. within the openings in thetrimjf'; and felly until it projects sufficiently-external., to said felly to'permit ,the bolt to beldrawn; fully into position. The 'removed portion'. cfg-the shoe can then be re laced Within the-rim, .the

ring 10 and blocks eingsuflicientlyloose for this dpurp'ose, after which the nuts 38 are applie to draw the bolts home, andthus securely clamp all, the parts together.. t festlv the parts can be readily disconnected by. sim lv reversi 0 theseries of Vo erations` P ne P immediately before described.

As the itive retention of the bolts against accidental loosening. is ofi-the highest importance', the nuts 38 have' a lock' associated therewith, .This lockmayinvolvevarius forms, the provision disclosed for such 'pu se consisting in' roviding each b olt wit 1 right and left han screw portions, one

'ofwhich is engaged by the nut 38, While the other takes a nut- 48, preferably ofsmaller size4 to facilitate its independenf adjustment or removal and which Will operateto -prevent the companion nut 38 from turning in a manner well nown inyother applications of this device.

Still referring to the construction illustrated in Figs. Land 2, each bolt has an axial duct 44 therethrough and establishing communication between the atmosphere andthe tirefinterior. Vertically-elongated openings l45 in eac-.h b oltfintersecting the duct therem likewise provide for atmospheric communication with ,the spaces or chambers '34 by- Vw'ayof thel slot 42 and passage presented by the clearance immediately below each block.I

Mani- IIO izo`

The various ducts, openings, and passages of the wheel serve for the admission of air to the tube interior and chambers-34-t-o reduce the heat engenderedthrough frictional stress ofport-ions will effect the induction ot fresh and cooler air for absorbing andsubsequently carrying olf a considerable percentage of any heat that may be developed. The cooling effect of the air will be appreciably augmented by the presence of numerously-distributed apertures 46 47 in the free part of the ring and supplemental section 13, respectively, and alternately disposed to secure abafliing circulation of the air in the immediate vicinity of the tread. l

When the wheel is in service, the alternate expulsion and induction of the air proceed continuously around the entireconstruction, the advantages ensuing from each expulsion and induction being experienced at the period -when and oint Where most re uiredi. e., a part of t ie construction Whic i either is or" immediately has beenin bearing relation with the surface over which the wheel is traveling. The objectionable admissionof dirt and other foreign matter to theducts, &c., can be obviated by the application of a suitably-conditioned cap 9 to the `projecting end of-each bolt. V

In Fig. 3 the peculiarly-funct'ioned,split tubular ring l()a is shown ,as being embodied in connection with a tire structure of the pneumatic type. In this constructionan inlia-table tube-50 is confined Within the tubular ring, and in order to provide for the convelr'ent. securement of the parts together and at- 11" sf e timemaintain the lintegrity of the air #tight character of the tube 50. the ring 10a, bloc-k 32a, rim 30a, and felly35a 'contain longitudinal slots 54. 55. 56. and 5T.

respectively, vertically registering with each other. as indicated inFig.S. The bolts S6a in this embodiment ofthe invention are solid. and each has a transversely-extending head 37a. rounded on its upper and lower sides and of such size that with the bolt held to present said head longitudinally at the inner side of the felly such head and bolt can be passed successively through the felly, rim. block. and ring `and then hy a quartereturn of the bolt its iead be caused to span the slot in the ring to become engaged with the latter. and thus be positively retained against with drawal. All of the bolts having been similarly engaged, the base .portion 2'7a of the shoe 22, which has meanwhile been removed from the rim, is replaced, the nuts 38 48 applied to lfirmly draw and retain the-.parts together, after which the tube 50 can be inflated, any of the ordinary devices being provided for such purpose.

Fig. 4 discloses a cushion form of the invention adapted for heavy service. Inthis arrangement the bolts 36" contain the axial ducts 44a to permit the expulsion and induction of the air with reference to the interior of the tubular ring 10b. For augmenting the strength of the construction the air-chambers 34 are dispensed with, theblocks 32h being arranged in close succession and bearing on the metal band-rim 30". The base portions 27" 27b of the shoe 22? are held by the independent clamp-plates 58 58, conjointly bolted to the felly b independent of the other parts, thus permitting one of the base portions 27b to be displaced lor the'shoe to be completely removed Without disturbing'the connected relation of said other parts.

The construction illustrated in Fig. 5 is in most respects similar t'o that. shown in Figs. 1 and 2, the tread portion ofthe shoe '22c being of different configuration and Vrounded to a more pronounced degree to adapt the wheel for a different characterof service.

In Fig. 6 the shoe 22d is of the rounded type disclosed in the receding ligure and is shown as being emp oyed in connection witha' cushion construction embodying the tubular spring-metal ring 10c z.and inner ma blc tube h, the parts being secured by the bolts 36, conditioned vand applied -in a manner similar to that described with reference .to Fig. 3.

Fig. 7 illustrates another cushion construc.

tion more particularly designed for heavy trafiic 'and comprises independent clampplates 59 59a for combining the base portions 2 7 27C of the shoe. This figure generally' discloses novel means for fastening the clamp-plates .to the felly 35 independently of the other parts, the bolts forming part of said novel means being each provided near one end with a shoulder 60, against which the adjacent plate 59a is held by a nut 61, engaged with a short threaded stem 62 oft-he bolt, projecting through a suitable opening in said plate. The other end portion 63 of each bolt contains a slot 65. which is of such length that an end portion thereof is designed to be Within the opening of the adjacent clampplate 59 when the latter is held against the felly. .\`o\\ by the insertion of a suitable Wedge 64 inthe slot both,l plates will be drawn and firmly held against the felly, one edgel of the wedge bearing against the metal at the outer end of the slot. While the other edge bears against the exterior face of the clamp-plate. The retentionof said wedge IOO IXO

'I .side to present edge 'portions one of which 1s can be Iassured by the insertion of a splitl key 66 through the smaller portion of the wedge. The excess of the slot, 6 5, or that part thereof whichis' within the bolt-opening, admits of a urther forcing movement of the wedge when' re uired to ta'ke up 'anylooseness of the clam .plates that mightbe occasioned b shrinh-age of thefelly, wear. of the part or through `any otherjcause.- through shrinkage is regarded as a remote contingency, as the fey material in the wheels of the present period is so well seasoned thati any cha occurs it is more liable to be due to a swe ing of the material, a condition which would obviously conduceto the more rigid clamping' of the plates ofthe fel.h
